# Electric batteries: Chinese manufacturers accelerate vertical integration > In China, several manufacturers are developing their own batteries, while Geely plans trials of semi-solid packs announced with a 1,000 km range and GAC announces its first solid-state batteries before the end of the year. BYD reaches full production of its Blade batteries in Shaanxi, and solid or semi-solid batteries are presented as the next technological step for electric vehicles. This movement alters the balance with major suppliers like CATL, with some manufacturers strengthening their partnerships or remaining dependent on massive supply contracts. The sub-events show no marked national difference: China concentrates most of the news, with Italy and Brazil covering the story. **In brief**: Ongoing story bringing together 12 events involving CATL, Geely, GAC Group and 4 more, in Chine, followed from 31 October 2026 to 3 November 2026. 20 articles from 6 sources (electric and batteries, plants, jobs and earnings); last updated on 3 November 2026 at 11:00. -
